To all whom it may concern:

Be itknown that I, THOMAS E.MAJoR,a citizen of the United States,residing at Maiden, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inMachines for Trimming the Edges of Upper-s within Shoes or Boots,ofwhich the following is a specification.

It is desirable in the manufacture of certain kinds of shoes to removetherefrom a portion of the edge of the lasted upper, or of the upper andlining, after it has been attached to the outsole. In the manufacture ofsuch a shoe a section of an insolenamely, the shank and heel endthereof-is mounted upon the bottom of a last, and there is also attachedto the bottom of the last a dummy half-sole section narrower than thebottom of the last, which extends from the shank. end of the insoleforward and includes the ball and toe. Upon these two sections, thefirst of which forms a permanent part-of the shoe and the second ofwhich is used only for the purposes of lasting,the edges of the upperand the lining are attached in lasting and as though the two sectionsconstituted an ordinary i11- sole. The lasted upper and the two-attachedsole-sections are then removed from the last, and the upper ispermanentlyunited to an outsole by a seam sewed by the McKay sole-sewingmachine or a similar machine or by any other fastening means which passthrough the edge of the upper within the shoe, close to the sidethereof, and through the outsole, preferably into a channel in itsundersurface. This uniting-seam extends through the rear part of thesole-section already referred to as forming a permanent part of theshoe; but it preferably passes beyond the outer edge of thedummy-section. The shoe thus made is then subjected to a further processby which the dummy-section and the overlapping edges of the upper andthe lining, which were lasted upon it, are removed, the edge or surpluspart of the upper and lining being severed from the main part of theupper and lining by means of a mechanism employing arapidlyreciprocating knife adapted to be introduced within the fore partof the shoe and to cut the edge of the upper and lining close to andwithin the line of the uniting-seam, but outside of the edge of thedummy-piece, from one end thereof,about the toe, to the other end, orcompletely around it. The dummy-section and edges of the upper andlining may then be readily removed. My invention relates to machinesadapted to thus out within the shoe or other inclosed orpartially-inclosed space. Machines for doingthis were patented by G. W.Day November 24, 1891, which patents are numbered, respectively, 463,947and 463,948, and my invention is an improvement in the class to whichthey belong.

My invention comprises an organization having, among other devices,first, a support or rest upon which the outsole of the shoe bears duringthe operation of a trimmingknife; second, a reciprocative cutter orknife above the said sole support or rest and a barcase and guide forthe same, which bar-case and guide are adapted to be moved laterallyfrom above the sole support or rest to a position at one side of thesame to permit the placing of the shoe over the lower part thereof andits removal therefrom, the cutter, casing, guide, and shoe being movabletogether to and from the operative position of the cutter over the solesupport or rest; third, a gage against which the edge of the sole of theshoe is adapted to be held and guided by the operator while theshoe-sole is upon the sole rest or support and during the operation ofthe trimming-cutter, which gage determines the line of the cuttingaction of the reciprocating cutter or knife in respect to the seam thatunites the outsole to the upper or other predetermined line, and thisgage when positively rotated may also act to assist the operator in thefeeding or presentation of the shoe to the cuttinginstrument; fourth,means for actuating the cutter and for latching the knife-case and guidein operative position and for unlatching them to permit them and theknife to be moved laterally; fifth, means whereby the unlatching of saidknife-bar case and guide also serves to automatically lift the knife orcutter in the case to its highest position or Within it, if the machinein coming to rest has not so lifted it, and for the purpose ofpreventing injury to the Work or the operator when moved laterally toits ini operative position or while it is being moved to and from suchposit-ion; sixth, means for adjusting the sole support or restvertically and horizontally and the sole-edge gage vertically andhorizontally, whereby the relation of these parts to each other and theline of reciprocation of the knife orcutter may be varied at the will ofthe operator.

It will be understood that the shoe is presented to the machine and fedright side up, that the bottom or under surface of the outsole restsupon the sole-support with its edge bearing against the gage, that theknife or cutter is held within the shoe by its bar casing or guide,which is shaped at the lower end to so locate it, and that the undersurface of the knife-bar case is not brought into contact with the uppersurface of the lining or bottom of the shoe, but that there is a clearspace generally between the under surface of the knife-bar case and theupper surface of the lining or bottom of the shoe. It will also beunderstood that the operator guides the shoe during the entire operationof the machine, whereby the above relation of the parts to each otherduring the entire cutting operation is maintained, and that where thegage is rotated it assists in that it helps to move the shoe.

Reference is to be had to the accompanying drawings forming part hereof,wherein Figure 1 is a view in side elevation of a ma chine embodying myinvention. Fig. 2 is a view in plan thereof. Fig. 3 is a view invertical section, on the line a: a: in Fig. 2, of the upper part of themachine.

Fig. 7 is a detail view, inverticalsection enlarged, representing the relation of the boot or shoeto the sole-support, the sole-edge gage, or the knife or cutter when thework is in operative relation to the parts and the parts in operativerelation to each other. Fig. 8 is a detail view, in horizontal section,upon the dotted line .2 z of Fig.

A indicates the stand or frame of the machine. It is generally made intwo parts namely, the base a and the upper section ahaving at its topthe forward extension a and at its back the bracket a shown as integralwith section a. The extension (1, is hollow,and through it extends themain shaft B of the machine, which has suitable bearings therein andthereon. Means are provided for rotating shaft 13 and for quicklystopping its rotation. For this purpose the shaft B carries clutchmembers 1) b, the driving member I) of which clutch is also shown as abelt-wheel and which when disengaged from the driven member I) of theclutch revolves freely upon said shaft. The driving member I) also haslimited endwise movement upon shaft B. The driven member I) of theclutch is rigidly attached to the shaft and is engaged by the drivingmember Z) when it is desired to operate the machine. The means I haveshown for this purpose comprise rock lever b pivoted at b to the bracket(1 and connected with a foot-treadle B by a link or rod 17 the arm b oflever 1) being adapted to engage the driving member I). The depressionof the treadle causes the driving member of the clutch to be moved intoengagement with the driven member and to be held in such engagement bymeans of arm b and upon the release of the treadle a spring Z),connected therewith, draws the treadle up to remove the pressure of therocklever b ,from the driving member. The rocklever 11* also has an armcarrying a brake or block N, which acts against the driven member I) ofthe clutch when the treadle is used to check the rotation of the shaft Bafter the clutch members Zr and Z) are disengaged.

The shaft B is used to actuate a cutter or knife, and for this purposeat the front end carries a crank-pin c, which is connected by a pitmanor link 0 with a knife-bar e, located in a knife-case C, the knife-barcarrying a knife or cutterC'. As shaft Bis rotated rapidly and rapidlyreciprocates the knifebar and knife, I have represented said shaft asprovided with a counterbalance in opposed relation to the crank andknife-bar. The knife or cutter O is suitably secured to the bar 0. Theknife-bar case 0 may be said to have, for convenience, ageneral shape,on a diminutive scale, like the lower half of a case made to lit abanjo, with a head 0 sharply bent back, held upright end for end, faceout, with a cap and plate 0 covering the circular part and the upperhalf of the straight part and a plate e covering the lower half of thestraight part, the part c being uncovered on the lower side. The knifebar case is movably supported, and for this purpose from the center ofthe circular part a sleeve 0 extends over the main shaft on which it isjournalcd, the axis of the shaft B and the case C being concentric. c isa lug or car carried by the case 0, shown on top thereof, the lug or ear0 having a latching-recess 0 which is adapted to receive a locking-pin(1, shown carried by a rocker-arm (l The pin d and lug or ear 0 serve tohold the case C either vertically or slightly inclined from thevertical, as will hereinafter appear, and thus serve as a lock for thecase 0.

The circular and the straight part of case 0, as illustrated, form threerecesses of different depths. The first incloses the counterbalance 0carried by the main shaft, as well as the crank-pin c, and the sleeve orhearing of the pitman c journaled on it. The second recess is for theplay of the pitman, and the third and shallowest recess is for the upperand longer portions of the knifebearing bar 0'. The part 0 forms a coverfor the top and sides of the backwardly-projecting portion of theknife-bar 0, out from under which the bar reciprocates with the knife atits extremity and up and into which both are drawn when the device thatraises the locking-pin from its recess rotates the main shaft, ashereinafter shown.

It will be seen that the knife-bar is bent at its lower end inwardly anddownwardly, and thus carries the knife inside the shoe and thereoperates it. The bar may be reciprocated in any desired way. Theknife-case acts when rigidly locked in a fixed position as a guide tomaintain the knife bar or arm in its operative position of rapidreciprocating motion, and it also acts as a cover for said bar and as ameans for moving said bar laterally, the bar a being pivotally supportedby the crank'pin c.

The knife-bar case is represented in full lines in Figs. 5 and 6 in itslatched position and in Fig. 6 in dotted lines in its nnlatchedposition. In Fig. 5 the locking-pin d is shown in engagement with thelatching-recess c of the case, and in Fig. 6 it is represented asdisengaged from the latching-recess to allow the case to be moved fromthe position shown by full lines to the position shown by dotted lines.The locking-pin 61 projects horizontally from the arm 01 and the latteris carried by a rock-shaft d. The rock-shaft d is supported by brackets61, which project from the extension 0. (See Figs. 1, 2, and 5.)Rock-shaft d also carries an arm d that is connected with a treadle D byan arm D. The treadle D is held in its highest position by a spring (iand this serves to hold the locking-pin d in its lowest position or in aposition to automaticallyen gage the latchingreeess 0 when the case 0 ismoved from the position shown by dotted lines in Fig. 6 to the positionshown by full lines in Fig. 5. The lug c is extended upward upon oneside of the latching-recess to provide a stop beyond which the pin maynot pass, and upon the opposite side of the latching-recess it has theinclined surface 0 which serves to lift the locking-pin to allow it topass into recess 0 of lug 0 when the latter is moved from its lowestposition to its normal operative position.

It is desirable to stop the rotation of shaft B as soon as it isdisconnected from its driving devices, and for this purpose the shaft dalso has an arm a, that carries a roll or pin E, which roll or pin isadapted to engage the edge e of a heart-shaped cam E, supported by shaftB and shown carried upon the front face of the driven clutch member I).When the treadle D is moved downwardly, it lifts locking-pin d from therecess 0 of lug c and simultaneously brings roll E into engagement withcam E, thereby turning the shaft B sufficiently to operate the crank-pinand cause it to lift the knife-bar and the knife C totheirhighestposition, unless, of course,- the machine shall have stopped when thecrank is in such position. The edge of the heartoam has a return-curve,forming a recess 6 which permits the said roll or pin E to make its fullstroke either when the roll or pin acts to move the cam or when the camhas stopped with the said recess in line with the said roll or pin. Itwill thus be seen that the opera= tion of unlatching the knife-bar casepreparatory to the removal of the shoe therefrom automatically causesthe shaft and crank-pin to be turned, if the crank-pin is not already inits highest position, to lift the knife from the shoe into the lower endof the knife-bar case, thereby permitting the shoe to be removed withoutinjury to itself or to the knife and permitting the placing of a newshoe upon the lower end of the knife-bar case without injuring the knifeor shoe.

It will be understood that the shaft may be turned by the cam and itsactuating-pin, because at that time the shaft is at rest, the drivingmember of the clutch having been disengaged from the driven member. Theheart-cam E may be attached directly to the shaft B instead of to thedriven member of the clutch.

Beneath the knife or cutter O is a support or rest for the outsole. Sucha support is shown at F and which is indicated as inclined from itsupper endfdownwardly and outwardly, and it also preferably broadens fromits upper end. The support or rest F is adjustable vertically, andforthis purpose it is shown extending to the upper end of a slide f,which is movable for the purposes of adjustment in a vertical slidewayf'at the front end of a horizontal bracket F, which slideway is preferablyformed in the end of the bracket. The slide is so represented, and it iscovered by a cap-plate f The meansI have shown for allowing verticaladjustment of the slide and the sole-support comprise anadjusting-screwf having a head f which screw meshes in a threaded holein the cap plate f the outer edge of which head enters a recess fextending across the face of the slide f near its lower end. The slideextends below the bracket and cap in order to permit the engagement ofthe screw-head therewith and also for the purpose of locating the headof the screw in an accessible position. A set or look screw f is carriedby the bracket F and is adapted to be screwed against the slide tofasten it and the sole support or rest in a stationary position afterthey have been adjusted. The bracket F is adjust-ably attached to thesection a of the main frame, being shown so attached by a screw-stud fwhich passes through a slot f in the bracket, and by means of thisslotand the screw the bracket is enabled to be adj usted horizontally,which provides horizontal adjustments for the sole rest or support. Theinner end of the bracket is squared to fit a squared horizontal recessin the side of the frame, (indicated by dotted lines in Fig. 3,)although it may be otherwise supported thereon. To assist the operatorin guiding the shoe under the knife, I have shown a gage adjacent to theshoe-support. The gage H is located back of the sole support or rest andsomewhat above it,and it serves asa means for determining the line ofaction or cut of the reciprocating knife or cutter c in the shoe orarticle which may be held against it. It may be a stationary gage, or itmay be provided with rotation, in which event it becomes a feeding orantifriction gage, and when it is so employed I prefer to rotate it bymeans of a spirally-threaded wheel h on a shaft hand a spirally-threadedwheel 72*, the axis of which is at a right angle to the axis of thefirstnamed wheel and which is carried at the end of a hollow horizontalshaft h (See Figs. 1 and 4.) The said shaft h3 is supported at one endby a stud attached to a bracket 7L4 and at the other end by the bracket72. and said shaft has a beveled gear lbs, with which a beveled gear hat the lower end of a shaft 7L7 engages. This shaft 71.7 is in turnconnected with the main shaft B by means of a worm-wheel 7&9 at theupper end of shaft h meshing with a worm h upon the main shaft. (SeeFig. 2.) Shaft IL7 is journaled in suitable bearings carried by the mainframe. The gearing is of a size to provide the gage with relatively slowrotation. The gage is provided with means whereby it may be verticallyand horizon tally adjustable in relation to the sole support or rest F.It is vertically adjusted by means of a sleeve m, through which theshaft It extends, which sleeve has an exterior screw-thread m, screwinginto a threaded hole m at the forward end of a slide m The sleeve m hasan enlarged section or head M, by which it may be turned. It will thusbe seen that the support F and gage H are supported and adjustableindependently of each other, and it is evident that a skilful operatorcould guide a shoe on the support F under the knife without utilizingthe gage H as a guide.

It will be understood that the sleeve m furnishes a bearing for thegage-shaft h and that it also provides means whereby the gage-shaft andgage may be vertically adjusted. That this adjustment may be madewithout disengaging the threaded wheels h 7L2 the threaded wheel h ismade longer than would otherwise be necessary. A stud m extends throughan opening in the slide m and bears constantly against the outer surfaceof the sleeve m. It is pushed inward by a lever or arm at, pivoted at mand against which a spring m bears, so that the stud m is forced andheld by the yielding pressure of the spring against the sleeve.

The slide m has a round section m which slides and is held in opposedholes 127. in the frame A, and means are provided for adjusting theslide horizontally toward and from the sole-rest F. For this purpose Ihave shown an adj usting-screw m fastened to the frame A and extendingoutward therefrom, and an adj usting-nut m mounted upon said screw m andwhich engages the slide m by means of a forked connecting-arm mextending therefrom.

To permit the horizontal movement of the gage without disengaging thethreaded connecting-wheels h h the wheel 7L2 upon the horizontal shaftis made longer than would otherwise be required. The bevel-gear h ,thethreaded wheel h and their operating-shaft may be covered by a curvedcover-plate n.

It will be understood that when the gage H is not adapted to have rotarymovement the operating-wheels h 72. and shafts 7L3 h and theirconnecting-gearing may be dispensed with.

The operation is as follows: The knife-bar case having been moved tooneside of the shoesupport, theshoe is placed over the end of said caseand is then moved with the knife-bar case over the work support or rest,whereupon the knife-bar case is automatically locked and maintainedlocked with the knife-bar and knife in operative position within theshoe. The shoe-sole thus resting upon the sole-support its edge isbrought in contact with the gage, and this causes the inner surface ofthe sole and the edge of the upper to be separated from the undersurface of the knife-bar case. The machine is then set in operation andthe shoe is fed andguided by the operator in a manner to cause it to bepresented in any desired order of movement to the action of the cutter,which is rapidly reciprocating within the cavity of the shoe, and byadjusting the gage to any desired position and holding the edge of thesole in contact therewith the line of the cut made by the knife may bepredetermined. When a rotating gage is employed, the edge of the sole isadvanced by the gage, as well as located by it, so that the followingsections or parts of the sole edge are to adegree automatically gaged.

It is desirable that the knife be centrally located in respect to thesole-support and the gage. Nice fitting of parts would be necessary toso locate the knife were it not that means are provided whereby it maybe more readily accomplished. This result is obtained by making thelocking-pin (1 upon the arm 01 of the rock-shaft adjustable lengthwiseupon the arm, and a change in its position on the arm will of coursevary the position of the lower end of the knife-bar case of the knife.Any means for adjusting the pin horizontally may be employed, and I haverepresented as one means a longitudinal slot in the said arm d in whichsaid pin is horizontally movable, the pin being locked to the arm in anydesired place by a washer and nut.

I may say that the apparatus herein described may be used for trimmingout an ysurface material from tlie'interior of a shoe or other hollowarticle and that the details of construction shown and described may bevaried Without departing from the spirit of my invention.
